Abstract (en)
A method of fabricating composite fluoroplastic articles, the method comprising the steps of melting and blending together a melt-processible fluoropolymer and a liquid-crystal polymer having a melting point at least 20 DEG C higher than that of the fluoropolymer, orienting the blend so as to form molding particles comprised of the liquid-crystal polymer dispersed in a fibrous form within a fluoropolymer matrix, then melt processing the particles at a temperature of at least the melting point of the fluoropolymer but not above the melting point of the liquid-crystal polymer. Composite articles manufactured by the method have good moldability, low linear expansion coefficient and molding shrinkage, and excellent strength and deflection temperature.
